The invention consists in the novel con# struction and combinations of.the several parts, as will be hereinafter fully' set forth and pointedout in the claims.

Reference is to be had tothe accompanying drawings forming a part ofthis specification, in which similar figures and letters of referenceindicate corresponding parts in all the Figure'l is a partial plan viewand 'partial horizontal section of the roller. Fig. 2 is a,

front elevation thereof, one end being in vertical section and likewisethe tongue. Fig. 3-

is an end view of the roller; and Fig. 4 is a Avertical longitudinalsection taken essen-` tially on the line 4:' 4 of Fig, l.

In carrying ont the invention 'four hollow drums A, are usually employedinthe con- `between the hubs and the drums through the medium of spokes11 or their equivalents.

i 1 Then two sets of. rollers` aref conne'ctedb57- a 75,. crosssection-in orderV that'they `rnay't prop: erly in the boxes l5. Thusit'willbe observed that the frame "is'V vsomewhat rectangular ,in'

ablebearingsupon the platform; and the le- IOO crumed upon sleeves 26,carried by the rear bar 18 of the frame B, as the level' arms areadapted to be carried to and from the rear face of the drums A. Eachlever arm has secured to its lower end a scraper 27, the scraper beingof angular construction as is best shown in Fig. 3; and the scrapercarried by each lever arm isadapted to engage with one connected set ofdrums A, as shown in Fig. 1. The lever arms 25 are guided in theirmovement, being made to pass through eyes formed upon guide rods 29,also attached to the boxes and extending rearwardly therefrom in ahorizontal position, as shown in Fig. 2. Thus it will be observed thatwhen the driver presses against the treadles of the levers 22 and 23,the scrapers will be carried against the drums, and will remove from thedrums any soil that may cling thereto; while when the treadles are inthe upright position shown in Fig. 2, which is their normal position,the Scrapers are carried out of connection with the drums and occupy theposition illustrated in Fig. 3. It will be further observed that as theframe B is as it were, fulcrumed upon the connecting medium of the setsof drums, the roller may be readily drawn ahead over exceedingly roughor undulating ground Without injury or inconvenience to the team drawingit, since the drums will accommadate themselves to the inequalities ofthe ground and the frame will accommodate itself in the same manner. Thepole 30 is located at its rear end in a socket 31, formed upon thecentral portion of the front bar 17 of the frame, and braces 32,arranged in the shape of a truss are attached at their rear ends to thefront bar 17 near the ends thereof; and at the central portion of thetruss brace a socket 33, is formed, through which the pole is alsopassed. A ham mer strap 34, is connected with the pole between thesockets 31 and 33, through the medium of a removable pin 35; and thehammer strap is connected with the brace and with the pole by passing apin 36, also removable, through the socket 33 and the pole, as shownbest in Fig. 1. Thus it will be observed that the pole may be readilyremoved from connection with the roller when the latter is not requiredfor use. The drums may, as shown in dot-ted lines in the drawings, beprovided with spurs secured in either a positive or a removable mannerto their outer faces, and for example, the spurs may be attached tosegmental plates and the plates be secured to the drums. When the spursare employed the levers, the arms, the guides and the cleaners, are d1spensed with. The spurs make the drums effective clod Crushers. 0

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. ln a land roller, the combination, with a series ofdrums arranged end to end and at short intervals apart, shaftsconnecting each two drums, and a sleeve mounted loosely on each shaftand extending through both hubs of a drum, of a frame of substantiallyrectangular construction, the frame being pivotally connected with thesleeves, a truss brace connected with the forward end of the frame, andsockets formed upon the forward end of the frame and the truss brace,the said sockets being adapted to receivea pole, as and for the purposeset forth. l 2. In a land roller, the combination, with a series ofdrums arranged end to end and at short intervals apart, shaftsconnecting each pair of drums, and a sleeve held to turn upon each ofthe said shafts, the sleeves having boxes secured to their centralportions, of a frame of essentially rectangular construction, the sidebars of which are clampedin the boxes, a platform supported by theframe, foot levers journaled upon the platform, lever arms located belowthe platform, said arms being bifurcated at their lower ends andfulcrumed upon the rear part of the frame, a link connection between thefoot levers and the lever arms, guides supported by the frame, throughwhich the links and the lever arms have movement, and Scrapers carriedby the lower ends of the lever arms, each scraper being adapted forengagement with the rear portion of a pair of drums, as and for thepurpose set forth.,
